Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic analyzer for analyzing components in a biological sample, and more particularly to an automatic analyzer having a function for making the operation of the automatic analyzer simpler and more reliable. Is.

[0002]

2. Description of the Related Art In recent years, the number of clinical chemistry test items in automatic analyzers has increased, and diagnosis / treatment based on the data has been increased.
It is held for 4 hours. The automated analyzer is also becoming multifunctional, and a specialized operator who has received training uses it. However, under the present circumstances, when there is no specialized operator such as at night or on holidays, an operator such as a doctor or a nurse who is not accustomed to the device operates the device when an urgent inspection is requested.

The operation procedure in the conventional automatic analyzer is as follows.
It is as follows. A request for a patient sample is input from the screen on the operation unit, the sample is set at the position of the sample container array unit, and analysis is started.

[0004]

In the conventional automatic analyzer, the operator asks the operator which screen should be used for requesting the patient sample and at what position the sample should be installed. Since it was not presented, in the operation of inputting information about the sample (measurement item, position of the installed sample container array part, etc.) when requesting the measurement of the sample, the position where the sample is already installed may be entered, Accidentally remove the sample that has already been installed, even if it is an unmeasured sample or a sample waiting to be remeasured,
There is a problem that an error such as setting another new sample is likely to occur.

An object of the present invention is to provide an automatic analyzer which is less likely to be erroneously installed when a patient sample is installed.

[0006]

The automatic analyzer is roughly divided into an analyzing section and an operating section.

According to the present invention, the operation unit has an area for storing information for each position on the sample container array unit such as a sample measured by the analysis unit or unmeasured, and processing for each position of the sample container array unit. The unprocessed information is stored, the operation unit determines whether or not the position is installable according to the information, and automatically displays only the installable position on the screen.

The information for each position is, for example, "1. measured" for each position of the sample arrangement section of the analysis section.
It shows the information of the installed sample such as "2. Request item is registered but not measured", "3. Measuring", "4. Waiting for remeasurement", "5. End of output of result", etc.

[0009]

The function of the above technical means is as follows.

The cause of accidentally excluding unmeasured specimens in the sample container array section or specimens waiting for re-measurement or inputting an unusable specimen installation position is Because the installation position was not presented by the device side,
"1. Measured", "2. Request item is registered but not measured", "3. Measuring""4. Waiting for re-measurement"
It has an area to store position information such as “5. Result output end”, and stores the above information to make it possible to determine whether it is a position that can be installed in the device, and according to this information, automatically install only the installable position when requesting analysis. By displaying the screen on the screen, the erroneous operation can be prevented and the operation method can be facilitated.

It is assumed that an analyzable position is displayed in the initial state of the screen display.

Embodiments of the present invention will be described in detail below with reference to FIGS.

FIG. 1 is a schematic view showing an embodiment of an automatic analyzer to which the present invention is applied, and FIG. 2 is a view showing a processing example for displaying a sample installable position of a sample container array section,
3 is a configuration diagram of information belonging to each sample installation position in FIG. 2, and FIG. 4 is an example of a screen displaying the sample installable position in FIG.

An automatic analyzer according to an embodiment of the present invention will be described.

In FIG. 1, a sample container 1 containing a sample
Are installed on the sample disk 2. The sample disk 2 is controlled by the computer 3 via the interface 4.

Further, the sample disk 2 is rotationally moved below the dispensing probe of the sample mechanism 5 according to the order of the samples to be analyzed, and the sample in the predetermined sample container 1 is connected to the sample dispensing mechanism 5. A predetermined amount is dispensed into the corresponding reaction container 6 in the reaction container row by the sample pump 7.

The reaction container 6 into which the sample has been dispensed is a reaction tank 9
To the first reagent addition position. A predetermined amount of the reagent aspirated from the reagent container 12 is added to the moved reaction container 6 by the reagent pump 11 connected to the reagent dispensing probe 8.

After the addition of the first reagent, the reaction vessel 6 moves to the position of the stirring mechanism 13 and the first stirring is performed.

Addition and stirring of such reagents are performed for the first to fourth reagents.

The reaction vessel 6 in which the contents are stirred passes through the light flux emitted from the light source, and the absorbance at this time is detected by the multi-wavelength photometer 15. The detected absorbance signal is A
The signal enters the computer 3 via the interface 4 via the / D converter 16 and is converted into the concentration of the sample.

The density-converted data is printed out from the printer 23 via the interface 4 and displayed on the screen display unit 21. 24 is a floppy disk.

After the photometry is completed, the reaction vessel 6 is moved to the position of the washing mechanism 19, the inside of the vessel is discharged by the vessel washing pump 20, then washed with water, and used for the next analysis.

Analysis items and analysis conditions can be input for each sample using the screen 21 or the keyboard 22.

Next, the processing for displaying the sample installation position of the sample container array section will be described.

In FIG. 2, the computer of the operation unit is
It has a position information storage section and an installable determination section, and when it is confirmed that the sample installation position of the sample container array section is in the installable state, the corresponding position number is displayed on the screen of the screen display section 21 of the operation section Encourage the installation of analytical samples.
When the sample registration is completed, the above operation is repeated for the next position. If the position information is in a state where it cannot be installed, the corresponding position number is skipped and the information of the next position is confirmed.

Next, the information of the sample installation position of the sample container array portion is the position number 31, position state 3
2, the installable flag 33. The position number 31 is the sample installation position number of the sample container array section. The state 32 of each position is a state such as "no sample", "position registered", "measurement in progress", "waiting for re-measurement", "measurement end", or the like. The installable flag 33 is
If the status of the above-mentioned position is a state in which it can be used for new measurement such as "no sample" or "completion of result output", it becomes "ON". "OFF". The information on this position is sent to the computer 3, and the apparatus judges whether the position is ready for installation.

Next, a screen for displaying the sample setting position will be described.

In FIG. 4, the sample installation position which is determined by the process shown in FIG. 2 that the sample installation is possible is displayed in the sample installation position display area 41.
The operator can install the sample at the position displayed in the sample installation position display area 41 and start the analysis. In the initial state at the time of transition on the screen, the position of the sample array portion that can be analyzed is displayed.

In the automatic analyzer to which the present invention is applied, the operator is required to confirm, for example, whether the sample is an unmeasured sample or a sample waiting for re-measurement because the displayed sample installation position is always the installable position. Instead, a new sample can be installed in the sample array section. Even if the sample is installed at that position, the sample is in the “measurement completed” state, so that the sample can be removed and the corresponding position can be used for registration of a new sample.

[0030]

According to the present invention, information on the position of the sample container setting section is stored, the installable position is determined based on the information, and only the installable position is automatically determined when a sample measurement request is made. Since it has a function of displaying on the screen, it is possible to provide an automatic analyzer which is easy to operate and has less erroneous operations.
